It is OK to give patients and potential patients, easy access to you.
I find that a WhatsApp number works well.
It doesn’t mean that you are liable for an emergency call at 3am. You make it clear that it is just another way to get in touch with your practice.
I think a lot of us are worried that we will be hounded at all hours, so we put up blocks and make things difficult for patients to get in touch.
If you try it, you might be surprised that you are not as inundated as you might think and it is just a way of lowering the barrier to entry to your practice.
